Therefore, each initially stimulated B cell produces a clone of plasma cells, all producing the same specific antibody.

因此，最初每个被激活的B细胞产生1对浆细胞，二者都产生相同的特异性抗体。

In the final stage of antibody development, antibody-producing B cells recognize specific parts of a pathogen and then mutate, or mature, so the antibody can bind to the pathogen more firmly.

在抗体发育的最后阶段，抗体生成B细胞识别病原体的特定部分，然后变异或者成熟，所以抗体可以结合病原体更加牢固。

They both proliferate, increase in number, and they differentiate; they differentiate from immature B-cells into antibody producing cells.

In the case of the helper cells they stimulate a specific population of B-cells to mature into antibody producing cells, and that antibody is generated against the antigen that stimulated it.

以辅助性T细胞为例,辅助性T细胞刺激特定的B细胞,使这些细胞成长为抗体分泌细胞,抗体分泌细胞产生大量的抗体,以消灭大量增殖的抗原

Now, these Th-cells, helper T-cells, go on to stimulate B-cells, and it's these B-cells that become the mature antibody producing cells that make quantities of antibody that fill up in your body.

这些辅助性T细胞,进一步刺激B淋巴细胞,从而使这些B淋巴细胞,逐渐发育成成熟的抗体生成细胞,可在体内产生大量抗体
